Benefits of technology

The patent text describes a method for creating a durable and smooth coating on a surface using an organic-inorganic complex forming composition. This composition includes an organic silicon compound and a thermosetting compound. By blending these two compounds, a polysiloxane layer can be formed on the surface, allowing for further layers of materials to be added. The technical effect of this method is a more efficient and effective coating that can protect and enhance the appearance of surfaces.

Problems solved by technology

However, a hard coating property of a film of a trifunctional silane is not sufficient.
Therefore, a tetrafunctional silane and colloidal silica are mixed with the trifunctional silane to compensate the hard coating property, but there is a problem that, if the film is cured, the film easily cracks and adhesiveness becomes worse.
Conventionally, a problem has been that, in a decoratively-deposited plastic container or the like, poor adhesion often occurs between a metal deposited film and the plastic container, thereby causing peeling of the deposited film.
However, a problem was that manufacturing cost is increased and a high degree of skill is required by increasing the number of layers.
Therefore, an anchor coat agent that can be used as an anchor coat for a plastic container and an inorganic film by one layer has been studied, but an organic-inorganic complex film disclosed in patent document 6 requires UV irradiation, and a problem was that a uniform UV irradiation technique for a three-dimensional plastic container is needed.

1) Preparation of Polysiloxane

[0140]17.00 g of methyltrimethoxysilane (Shin-Etsu Chemical Co., Ltd., KBM-13) was charged in a 140 mL mayonnaise bottle. 3.02 g of diisopropoxybisacetylacetonatotitanium (Nippon Soda Co., Ltd., T-50, the amount of the solid content in terms of TiO2: 16.5 wt %) was added so as to be 5 mol % in terms of TiO2 with respect to methyltrimethoxysilane. 19.91 g of MIBK was charged and stirred for 15 minutes (rate of stirring of 100 rpm).

[0141]4.50 g of distilled water was charged so as to be 2 times the mole of methyltrimethoxysilane, and a hydrolysis reaction was performed (2 hours, rate of stirring of 100 rpm). The liquid temperature rose to 40° C. at this time. After completion of the reaction, the reaction liquid was left for 30 minutes until the liquid temperature became 25° C.
